HOT-WATER HEATING SYSTEM.

Specification of Letters Patent.

Patented Dec. 29, 19ML.

Application led December 28, 1912. Serial No. 739,023.

To all 'whom 'it may concern Be it known that l, ADOLPH SCHWARTZ, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of lennsylvanim have invented a new and useful llmprovement in HotllV'ater Heating Systems, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a. hot water heating system adaptable for application to, or use in connection with, an ordinary kitchen range.

More specilically the object of my invention is to apply to, or incorporate in, an ordinary range such a construction and arinngement of water backs and connections as will enable water to be heated in such v lume and to such temperature as will sullice for the heating of radiators located in the different rooms of the house and connected with the said water backs by appropriate pipe connections.

il further object of the invention is to provide such an arrangement of water backs and connections as will effect the heating of water as above specified for the hot water radiators and, at the same time, effect the heating of the usual` volume of water for kitchen and bath purposes.

ik. further object of the invention is to effect the heating of hot water for the above described purpose without interference with the utilization in the ordinary way of the range for cooking purposes.

i further object of the invention is to enable `the contrivances for heating all the water intended for both the hot water radiators and the boiler to be utilized entirely for the purpose of heating water for the boiler at such times as it is desired not to heat the radiators but to furnish hot water for the boiler in unusual volume and at a more than ordinarilv high temperature.

|The invention consists of such construction and arrangement of water backs and connections between the same and the boiler and the radiators as will enable the above defined objects to be eected.

The nature of the invention will be better understood by reference to the following description and to the accompanying drawings, in which- Figure l is an elevation, partly in section andpartly in diagram, illustrating the en tire system. F ig. 2 is a plan view of the water backs and pipe connections thereto. Fig. 3 is an elevation of the water backs and pipe connections thereto.

rlhe range e is provided with the usual grate l) below the lire box, the ash pit c and the oven (Z. As is usual, a water back is l0- cated within the fire box. l have, however, substituted for the ordinary construction of water back a special construction of water back which is best adapted to cooperate with the other elements of my system to produce the results desired. As will be observed by reference to Fig. 2, this water back extends entirely around the fire box and is divided by the partition e into an upper chamber f and a lower chamber g.

The supply pipe h from the cold water main is branched, as shown in F ig. 3, which branches connect respectively with the upper chamber 7 and the lower chamber g of the wat-er back. Preferably the partition e, in one of the four legs of the water back, is oriiiced at z' to establish communication between the two chambers f and g.

A pipe j extends from the lower chamber g of the water back to the boiler le. Another pipeZ extends from the upper chamber of the water back to the supplemental water back m, hereinafter described.

It will be observed that the cold water connection is established at the beginning of the first leg of the main water back and that the connections from the main water back to the boiler if: and to supplemental water back m are at the end of the fourth leg of the water back. There is no direct communication between the first leg and the fourth leg, so that the water entering chambers f and g of the water back must necessarily circulate throughout the entire length of said chambers before it can pass therefrom to the boiler and supplemental water back respectively. y

The supplemental water back, above mentioned, is arranged above the fire box and oven and below the top of the range. It

extends in a horizontal plane and consists preferably of a section which in construction bears a general resemblance to an ordinary radiator section in that it has laterally extending end tubes m1 and one or more intermediate tubes m2 and a series of longitudinally extending tubes m3. Between the longitudinally extending tubes m3 a suflicient space is left so as not to obstruct soy the passage of heat to the stove lids and therefore not interfere with the use of the stove for cooking purposes.

The water entering the supplemental water back by the pipe Z has already been heated to a substantial temperature during its passage through the upper chamberl of the main water back. The water enters the supplemental water back at the end thereof over the fire box and leaves the supplemental water back at the other end thereof, through the pipe n. This pipe n is provided with branches o, 29, and Q, leading to radiatorsl w located at different portions of the house, as, for example, on the several floors thereof. The return connections from the radiators connect through the pipe d with the lower chamber g of the main water back.

It will thus be seen that ample provision is made for supplying the usual quantity 'ofwater to the boiler, and that special provision is made for heating an adequate volume of water at a maximum degree of temperature for the heating system. It will also be observed that the arrangement of the main and supplemental water backs does not interfere with the utilization of the range for cooking in the ordinary way.

At certain times it may be desirable to supply an unusual volume of hot water to the boiler. I have provided means whereby this can be effected. A pipe s connects the pipe n with the boiler is. The pipe s has the valve t. The pipe y' through which the water to the boiler is normally conveyed has a valve fv. By closing the valve o and opening the valve t the water, before it enters the boiler, must necessarily flow through the water back f g and thence, through pipe Z, supplemental water back m and pipe s, to the boiler; whereby a practically unlimited amount of hot Water may be furnished to the boiler.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a hot water heating system, the combination with the range containing .fire box and oven, of a main water baclt in the lire box, a horizontally disposed supplemental water back located beneath the top of the range, a pipe connected to the main water back and adapted for connection .to

the source of Water supply, a pipe connected to the main `water back and adapted for connection to the boiler, a connection between the main-water back and the supplemental water back, and pipes connected recombinationV with the range containing fire i box and oven, of a main water back in the fire box, a horizontally disposed supplemental water back located beneath the top of the range, a pipe connected to the main water back and adapted for connection to the source of water supply, a pipe connected to the main ywater back and adapted for connection 'to the boiler, a connection between the main water back` and the supplemental water back, and pipes connected respectively to the supplemental water back and to the main water back and adapted for connection with the supply and return to radiators, and a* valved pipe connected with the first of the last named `pipes and adapted for connection to the boiler'.

` In a hot water heating system, the combination with the range containing `fire box and oven, of a main water back in the fire box extending substantially around the innerv wall of the fire box but with non-communicating ends, a horizontally disposed supplemental water back located beneath the top of the range, an inlet pipe connected to one end of the main water vback, an outlet pipe connecting the other end of the main water back with the` supplemental water back, a pipe connected to the last named end ofthe Vmain water back and adapted for connection to the boiler, and pipes connected respectively to the supplemental water back and to the first named end of Vthe main water back and adaptedV Copies of this patent may be obtained for ve cents each, by addressing the Commissioner ci Patents,
